Performance in Intel IOMeter FileServer and WebServer Patterns

FileServer and WebServer patterns were used to test the performance of our RAID array under the workload typical of file- and web-server disk subsystems.

First of all, let’s take a look at the results our RAID array achieved in FileServer pattern:

RAID 0 array is faster when working with Promise controllers. With these particular solutions the performance growth of the array is evident even at queue=4. With ITE IT8212F and VIA VT6410 controllers the performance starts growing noticeably only when queue=16.

The overall performance indexes show that Promise controller are almost 1.5 times faster than ITE IT8212F and VIA VT6410.

The situation remains practically the same even when we shift to RAID 1.

The overall performance diagram for all four controllers working with our array, shows that the performance gets slightly better in case of Promise controllers compared with what we saw by RAID 0. ITE IT8212F and VIA VT6410 lose to their rivals even more than by 1.5 times.
